PAOS Request Error not handled correctly
The PAOS 2.0 specification Sec. 9.4 states that in case of an error while processing the PAOS request, the server is not able to send a SOAP fault. The additional HTTP request should be sent by the app.
If processing of the PAOS request message fails, the processor has no opportunity to send a SOAP Fault or any other message back to the PAOS requester. In this case it is RECOMMENDED that the user agent resubmits the HTTP request of step 1 (see Section 5), omitting any indication of PAOS support (such as the PAOS SOAP header block, or the PAOS HTTP header).
